3W LED DRIVER USER’S GUIDE Chapter 1. Overview 1.1 Overview Welcome to use LED driver series by Sure Electronics. This series provide users many choices: 0.5W, 1W, 3W, 5W and 10W, which integrate a MBI6651 chip by Macroblock – a high efficiency, constant current and step-down DC/DC converter. Featuring under voltage lock out (UVLO), over temperature protection, LED open-circuited protection and LED short-circuited protection, MBI6651 makes the drivers’ application safer. Additionally, to ensure the system reliability, the MBI6651 builds thermal protection (TP) function inside. This function protects IC from overheating in various applications. Thus LED drivers shall serve for longer time. This 3W driver features small size, high efficiency, stability, long service time and easy installation. LED dimming can be controlled via an extra pulse width modulation (PWM) through DIM pin. As many as 8 LEDs shall be connected in series. FIGURE 1-1 FRONT VIEW
